About zero, really. Unless some of those 80+ year olds are prominent scientists, etc. The numeric value $1 billion means $1 billion worth of human labor or energy. The amount of this energy is finite, and it's around $80 trillions currently. We can multiply it by 10-100, the exact number doesn't matter, what maters is that it's not a lot bigger than $1 billion. Saying that saving a human life is worth any dollar amount, is same as saying that our society, all 7-something billion people, should spend all their energy on saving that one life. A human body is really just a vehicle, like a car. When it approaches 80 yo mark, it's worth about nothing. It's just some people believe, with religious rigor, that they're bound to this car forever.
